Hi Joshua=2C
many thanks for your suggestion which I suppose would work perfectly=2C but=
I actually want iptables (CentOS 6.5 here=2C so no firewalld) rules in pla=
ce all the time=2C but only "MY OWN" iptables rules =3B>

Perhaps you could add the iptables and firewalld packages to yum.conf as ex=
cludes. I don't know if this would fail silently=2C but if so=2C the engin=
e installer would never know.
Thanks=2C

Hi Didi=2C
many thanks for your invaluable help!
I'll try your suggestion (/etc/ovirt-host-deploy.conf.d/99-prevent-iptables=
.conf) asap and then I will report back.
By the way: I have a really custom iptables setup (multiple separated netwo=
rks on hypervisor hosts)=2C so I suppose it's best to hand tune firewall ru=
les and then leave them alone (I pre-configure them=2C so the setup procedu=
re won't be impeded in its communication needs anyway AND I will always gua=
rantee the most stringent filtering possible with default deny ecc.).

Many thanks again=2C

Hi Didi=2C
I found the references to NETWORK/iptablesEnable in my engine logs (/var/lo=
g/ovirt-engine/host-deploy/ovirt-*.log)=2C but it didn't seem to work after=
all.
=0A=
Full logs attached.
I resurrected my Engine by rebooting the (still only) host=2C then restarti=
ng ovirt-ha-agent (at startup the agent failed while trying to launch vdsm=
=2C but I found vdsm running and so tried manually...).=0A=
OK=2C so it's host-deploy that's doing that.But it's not host-deploy itself=
- it's the engine that is talking to it=2C asking it to configure iptables=
.I don't know how to make the agent don't do that. I searched a bit the sou=
rces (which I don't know)=0A=
and didn't find a simple way.
You can=2C however=2C try to override this by:# mkdir -p /etc/ovirt-host-de=
ploy.conf.d# echo '[environment:enforce]' > /etc/ovirt-host-deploy.conf.d/9=
9-prevent-iptables.conf=0A=
# echo 'NETWORK/iptablesEnable=3Dbool:False' >>
/etc/ovirt-host-deploy.conf=
.d/99-prevent-iptables.conf
Never tried that=2C and not sure it's recommended - if it does work=2C it m=
eans that host-deploy will not=0A=
update iptables=2C but the engine will think it did. So it's better to find=
a way to make the engine not dothat. Or=2C better yet=2C that you'll expla=
in why you need this and somehow make the engine do what you want...=0A=
